I am at the 4th iteration on the pixel inspector and light path debugging tool. Eventually I moved the path collection to the GPU, so I don't have to toggle between CPU and GPU rendering, making the visualization fully interactive.

That looks extremely useful and well done! Totally stealing it for my future renderers :D

nice, I always wanted to have such a feature in the renderer!

Hehe. Me too, I don’t have much time available to fix light transport issues; good visualization, plus the ability to repeat the path on the CPU with a debugger are key.

"This will be the [fourth] time we have [rewritten] it, and we have become exceedingly efficient at it" Well done!

Hehe, more like the fourth time I come back to the feature adding bits and improvements. Actually, this is still using the first implementation core 😄

Wow that’s super neat, so the path collecting visualization is all gpu, no readback inbetween? 😃

It does read back. The paths visualization is rasterized on top of the path traced image. But the earlier iteration was running on a matching CPU path tracer.

Monad Testnet Visualized (Pt 3) I think Claude and I have fixed the freeze/pause issue. Works a lot smoother and most of the jitter is now just due to my GPU/CPU begging for mercy trying to handle the data visualization

Breaking down the difference between CPU and GPU. This is such a joy to watch.

I tested this on the 4070 Super, and while there is a performance difference, it’s not huge. The GPU also pulls more power on the older driver. If you’re using Path Tracing and have a higher-power 40 series GPU, it’s still worth trying, you might see a bigger performance boost.

Stress testing Metropolis 1998! - Population: 53,500 - CPU FPS: 80 - GPU FPS: 10-80 - RAM: 3,100 MB So: At the moment, the game is GPU bound. I know why and there's a lot of room for improvement. It will involve developing or customizing an existing GPU framework. There's also a lot of room to improve CPU/RAM, but right now it's in an okay place. #gamedev

After improving my GPU driver patch, the iOS VM now has fully* working Metal rendering 🥹 * WebKit rendering is still broken, but it's the only broken thing I could find

I tried Motorstorm on RPCS3 and can confirm it is playable. However, terrain deformation is extremely taxing on the GPU so I can't have 60 FPS at 1440p on my RTX 3070. You will have to either drop the resolution or lock the framerate to its original 30 FPS cap.

Today I release new GPU Particle Volumes system and the GPU Snow Particle shaders for it! This snow shader can render hundreds of thousands of particles at the same time even on a weak GPU. It also supports VRC Light Volumes. Get it on my Booth or Patreon!

"Use the GPU to optimize the rendering" >30fps on a 1000x1000 map. Absolutely crazy. The switch to simplified hexagons (solid color) isn't even needed btw, I just think it looks cleaner.

As of today, the Phoenix Suns have failed their fans, Devin Booker and Kevin Durant. There IS a path towards redemption, but from what I have seen so far, I am not confident in the Suns following that path.
